Mark 13:28-32 New Revised Standard Version (NRSV)
The Lesson of the Fig Tree
28 “From the fig tree learn its lesson: as soon as its branch becomes tender and puts forth its leaves, you know that summer is near. 29 So also, when you see these things taking place, you know that he[a] is near, at the very gates. 30 Truly I tell you, this generation will not pass away until all these things have taken place. 31 Heaven and earth will pass away, but my words will not pass away.
The Necessity for Watchfulness
32 “But about that day or hour no one knows, neither the angels in heaven, nor the Son, but only the Father.
